2 years ago I had my house extended and specified 'matching brickwork'. The
builder supplied some lighter bricks and said they were the best match.
Subsequently I found a much better match (almost indistinguishable - thanks
very much FNA Special projects - so much for your 40 years 'experience' in
the building trade!!) from an extension that was done down the road that was
not done by a cowboy. So despite Franks assurances that the bricks would
darken with age I am left with an extension that looks like an extension not
part of the house. I found that applying waterproof woodstain and
preservative to the surface of a few 'test' bricks worked well in darkening
the bricks so i wondered if there was on the market any special stain that
could be used? its a bit of an arse having to stain each individual brick
but worth doing to rectify the poor performance from a less than
professional builder. I did find the stain worked extremely well on the cut
edges of the bricks where a new window had been installed but I don't want
any problems with 'running' when it rains.
